MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 3.7KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load.

In order to adapt to the new material diversification, the machine adopts the most cutting-edge technology, more than ever more slim hard MITSUBISHI FR-F720-3.7K.
In order to be able to realize the fine cutting, grinding on the hard and hard material,
The need for high-speed operation has become more and more strong
FR-F720-3.7K
In order to cope with the increasing demand of logistics, every port in the world has a crane in every day.
A container filled with cargo.
We can achieve a new type of inverter products under the conditions of low speed and high torque to achieve smooth cargo handling operations,
Carry on the smooth movement to the heavy MITSUBISHI FR-F720-3.7K. MITSUBISHI inverter series: FR-F820.

Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel MITSUBISHI FR-F720-3.7K. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on.
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 355KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor.
Why is the frequency of the inverter voltage proporttional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the mmotor FR-F720-3 FR-F720-3.7K. 7K.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
